Ingredients for Lemon Crumb Bars
To make these mouthwatering Lemon Crumb Bars, you’ll need a few simple ingredients. Let’s break down the list:
For the Crust
- 2 ⅓ cups all-purpose flour
- ½ cup granulated sugar
- ½ cup light brown sugar, packed
- ¾ teaspoon salt
- ¼ teaspoon baking powder
- 12 tablespoons unsalted butter, melted and cooled
For the Lemon Filling
- 1 (14-ounce) can sweetened condensed milk
- 4 large egg yolks, room temperature
- 2 tablespoons heavy cream
- ⅛ teaspoon salt
- ⅔ cup fresh lemon juice (about 4–5 lemons)
Instructions for Making Lemon Crumb Bars
Preheat Oven
Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, leaving some overhang on the sides for easy removal.
Make the Crust
In a large bowl, combine the all-purpose flour, granulated sugar, brown sugar, salt, and baking powder. Stir in the melted and cooled butter until the mixture is crumbly. Reserve 1½ cups of the crust mixture for the topping, then press the remaining crust firmly into the bottom of the prepared baking pan.
Bake the Crust
Bake the crust for 12–15 minutes, or until it’s lightly golden. Remove the pan from the oven and let the crust cool slightly.
Prepare the Lemon Filling
In a medium bowl, whisk together the sweetened condensed milk, egg yolks, heavy cream, salt, and fresh lemon juice until the mixture is smooth and creamy.
Assemble the Bars
Pour the lemon filling evenly over the pre-baked crust. Crumble the reserved crust mixture over the top of the filling.
Bake
Return the pan to the oven and bake for 25–30 minutes, or until the top is lightly golden and the filling is set.
Cool and Chill
Allow the Lemon Crumb Bars to cool completely at room temperature, then refrigerate them for at least 2 hours before slicing and serving.
Serve
Cut the chilled bars into squares and serve them up! These perfectly sweet, tangy, and crumbly treats are sure to delight any lemon dessert lover.

Tips for Perfect Lemon Crumb Bars
Choosing the Right Lemons
For the best flavor, use fresh, juicy lemons rather than bottled lemon juice. Look for lemons that are heavy for their size and have a bright, glossy skin. Avoid any lemons that are dull or shriveled, as they may be drier and less flavorful.
Storage Tips
Once baked and chilled, Lemon Crumb Bars can be stored in an airtight container in the refrigerator for up to 5 days. They can also be frozen for up to 2 months, making them a great make-ahead dessert option.
Serving Suggestions
These Lemon Crumb Bars are delicious on their own, but you can also top them with a dollop of fresh whipped cream or a scoop of vanilla ice cream for an extra special treat. They also pair beautifully with fresh berries or a cup of hot tea or coffee.
Nutritional Information
Caloric Breakdown
Each serving of Lemon Crumb Bars contains approximately 300 calories, with the majority of those calories coming from the crust and the sweetened condensed milk in the filling.
Health Benefits of Lemons
Lemons are a great source of vitamin C, which is an important antioxidant that can help boost the immune system. They also contain small amounts of other essential vitamins and minerals, making them a relatively healthy ingredient in this indulgent dessert.
Variations of Lemon Crumb Bars
Adding Fruits
For a twist on the classic Lemon Crumb Bars, you can try adding other citrus fruits like limes or oranges, or even mixed berries to the filling. The possibilities are endless when it comes to playing with different fruit flavors.
Gluten-Free Options
To make these bars gluten-free, simply substitute the all-purpose flour in the crust with a gluten-free flour blend. You may need to adjust the amount of butter or other ingredients slightly to achieve the right texture.
Vegan Alternatives
For a dairy-free and vegan version of Lemon Crumb Bars, use a plant-based milk or cream in the filling, and substitute the butter in the crust with a vegan butter or coconut oil. You can also try using a vegan sweetened condensed milk alternative.
